Reference to other schema components.

There are mainly two different types of references. One is
the direct reference, which is only possible when schema components
are already available when references are made.
The other is the lazy reference, which keeps references by names
and later look for the component by name.

This class defines interfaces that define the behavior of such
references and classes that implement direct reference semantics.
